1.16 calculate relative formula masses (Mr) from relative atomic masses (Ar)
1.17 understand the use of the term mole to represent the amount of substance
1.18 understand the term mole as the Avogadro number of particles (atoms,molecules, formulae, ions or electrons) in a substance
1.19 carry out mole calculations using relative atomic mass(Ar) and relative formula mass (Mr)
1.20 understand the term molar volume of a gas and use its values (24 dm3 and 24,000 cm3) at room temperature and pressure (rtp) in calculations
1.21 write word equations and balanced chemical equations to represent the reactions studied in this specification
1.22 use the state symbols (s),(l),(g) and (aq) in chemical equations to represent solids, liquids, gases and aqueous solutions respectively
1.23 understand how the formulae of simple compounds can be obtained experimentally, including metal oxides, water and salts containing water of crystallisation
1.24 calculate empirical and molecular formulae from experimental data
1.25 calculate reacting masses using experimental data and chemical equations
1.26 calculate percentage yield
1.27 carry out mole calculations using volumes and molar concentrations
